Abstract (en)
[origin: US4399104A] The invention relates to a method and a device for producing a reaction mixture from flowable foam-forming or solid-forming components (preferably polyurethane forming components) which are conveyed continuously and are mixed together or are circulated. The quantity to be conveyed is preselected. The injection pressure is preselected and the circulatory pressure is measured for each component. The predetermined quantity and pressure to be conveyed as well as the measured value are preferably fed into a control computer during the circulation and the mixing process and are compared with actual values. Cavities are filled out with the reaction mixture produced and, in particular, molded articles are produced in molds.
